+
+### DeleteWizard
+
+Establishes a context, and only renders the `activeStep` (managed internally, or provided with the `activeStep` prop). Accepts a `DeleteWizard.Header` and any number of `DeleteWizard.Step`s as children.
+
+`DeleteWizard` and all sub-components include template styling.
+
+### DeleteWizard.Header
+
+A convenience wrapper around `CanvasHeader`
+
+### DeleteWizard.Step
+
+A convenience wrapper around `Wizard.Step` to ensure the correct context.
+Like the basic `Wizard.Step`, of `requiresAcknowledgement` is true, the step must have `isAcknowledged` set in context, (or passed in as a controlled prop) for the Footer's primary button to be enabled. (see the Wizard and DeleteWizard demos in Storybook)
+
+### DeleteWizard.StepContent
+
+A styled `div` for use inside a `DeleteWizard.Step` to ensure proper page scrolling and footer positioning
+
+### DeleteWizard.Footer
+
+A wrapper around Wizard.Footer with embedded styles for the DeleteWizard template
